Malicious Software


Dear All,

Below is the message from our IT security team. seek your feedback.

The sourcetree software is a malicious one and It sends http without http header, some Chinese binary in there (may be they have Chinese developers or Chinese variations of the software?)

Kindly request Altassian to confirm if this is safe (meaning untampered) Please provide the sandbox report and the hash below. I will approve as soon as they confirm that it is safe.

Hi, welcome to the Community!

While we don't publish a list of md5 hashes for Sourcetree on the actual site, I can confirm the hashes for the 3.3.9 Windows installer for you:

md5 12ad58ccaf4b2eff9a9e76d1b77ea9c9 SourceTreeSetup-3.3.9.exe

sha256 ffaef30ad57ab28aefb4dec307af0bdccdb81a99d1e345f2a7f4030dcc48f874 SourceTreeSetup-3.3.9.exe

In Windows, you can use the Get-FileHash powershell cmdlet to generate the file hashes and compare them against the values I've posted here. By default, it will give you the sha256 hash. You can specify a different hashing algorithm if you want to check md5 also:

Get-FileHash C:\path\to\SourceTreeSetup-3.3.9.exe -Algorithm MD5


Dear Daniel,

Thank you for the response. Is this an opensource project or this project is maintained by Atlassian? Just wanted a confirmation that this is a safe product to be installed in the enterprise network.

Hi Kiran,

While Sourcetree does contain code from open source libraries (a complete list is available in the Acknowledgements page in the application), the application itself is fully controlled by Atlassian. All development is done by Atlassian employees and we include a step in our build process to scan binaries for malware before the installers can be uploaded to the public website for download.


Thanks Daniel. Appreciate your quick response.
